Aoi and Haru have been navigating a secret romance, keeping their relationship carefully hidden from the rest of their school. However, the quiet normalcy of their hidden bond begins to fracture when Aoi notices that Haru has grown increasingly anxious, burdened by an unspoken worry she refuses to share. The tension culminates in a sudden tragedy when, the very next day, Aoi witnesses Haru plummet from the roof of the school building. In the devastating aftermath of her fall, Aoi uncovers a cryptic clue left behind specifically for him. Hidden inside his locker is a detailed relationship chart meticulously compiled by Haru herself. This document maps out the social connections within their school, but it carries a chilling warning: five specific individuals on the diagram are explicitly marked as "clowns." According to Haru's notes, these five people are not mere classmates or acquaintances—they are active conspirators who have been plotting to kill her. Now, armed with this unsettling map of secrets and motives, Aoi must unravel the dangerous truth behind Haru’s fall and identify the threats hiding in plain sight.
